SPECIFICATION forming part of Letters Patent No. 704,743, dated July 15, 1902.

Application filed April 9, 1902. Serial No. l0 1,979. (No model.)

To all whom it may concern.-

Be it known thatLJosEPH L. G1noUx,residing at Jerome, county of Yavapai, Arizona Territory, have invented an Improvement in Steam-Generators; and I hereby declare the following to be'a full, clear,-and exact descrip- My invention relates generating stean1,and itis especially designed for the employment of a fuel which can be continuously supplied and removed when exhausted.

Myinvention is especially designed for the utilization of the hotslag from smelting-furnaces and the like; but other forms of fuel may be employed in conjunction with a generator of this description. i

It consists of anannular, tubular, and horizontally revoluble shell, a continuous fire box or furnace-in the form of .anflopen channel fromone side, and means for continuously supplying the fuel-at one point, and means for removing it when theheat is exhausted.

My invention also comprises details of construction, which will be more fully explained by reference to the accompanying drawings, in vwhich 1 v Figure 1 is a part section and part elevation of a steam-generator embodying my invention. Fig. 2 is a portion of a plan of Fig.1.

a vertical axis, of ameans for removing the;

slag or other fuel when exhausted, means'for forming a closure for the furnaceduring its revolution, and means for supplying water tow the boiler and removing steam'therefrom.

As shown in thepresent drawings, my-generator is formed of short sections A, which may be made of any suitable or desired form in transverse sect-ion. Inl-thepresent'case I have shown these sections as rectangular, and

to apparatus for they are so formed andriveted together that by gears, as at 3, or equivalent means whereby thetubular shellcan be revolved around its center of rotation 23. t From the inner periphery ofthis annular shell pipes 4. extend upwardly at short intervals, connecting with an annular steam-drum 5, located above the wetter-chamber A. Other pipes 6 connect with A and extend up between the pipes 4 to a plane sufficiently above the top of the part A, where by elbows theyconnect with horizontal pipes 7, extending above the part A and atsuch a distance as to form a furnace and fuel-space between said pip'esand the top of A. Pipes 8 are con nected, with the outer ends of the pipes 7 by suitable angular couplings 9, so thatthe angular direction of the pipes 8 enables them to connect with the steam-drum 5. These connecting-pipes thusform a circulating systern between the partA and the steam-drum. A shield or closurelO extends from the inner periphery of the steam-drum to the inner and lower part of the chamber A, and a similar shield 10* covers; the inclined pipes 8, and the two shiel'ds' thus form an inelosnre for the pipes and in conjunction with the top of the part A thus form a furnace for the fuel. Elevated annular rims 12 extend around the outer and inner edges of the lower part of the furnace, and these rims serve to hold a. liquid or semiliquid fuel. In the present case I have designed to employ the hot slag discharged from smelting-furnaces, and for this purpose I have shown an inlet pipe or passage, as 13, which may lead from the settling tank or attachment of the furnace in which the metal is separated from the slag.

The slag is delivered through this passage into the generator furnace previously de scribed, and the generator is caused to revolve at a rate of speed depending upon'its size and upon the length of timethatthe slag will retain its heat; T-he slag isjremov'ed by means of a plow 14, fixed so as to project into the pathway of the slag, which it thus scoops out and deposits in the discharge-chute 15 to be delivered into cars 16 or in other desired manner. The plow may be adjusted by any suitable device, as the screw 17.

It will be understood that liquid hydrocar- -bon or other form of fuel could be used with good effect in a generator of this description,

the operation being essentially the same as the generator, I have shown tension-rods 19 with turnbuckles 20. or other equivalent means for adjusting them. The outer ends of the rods are firmly secured to the inner periphery of the annular generator-shell, as shown at 21, and the inner ends are secured to a hub, as at 22, which is mounted and turnable upon a central pillar or standard 23. In order to supply water to an apparatus of this description, I have shown the feed-water pipe 24 as extending up through the central pillar 23, having one or more branches, as 25, extending outwardly to the shell, connecting therewith at as many points as may be found desirable. A suitable packed joint, as at 26, allows the radial portion 25 of the pipe to revolve about the stationary vertical portion 24. Byasimilar arrangement steam is withdrawn from the steam-drum 5 by means of steam-delivery pipes 26, connecting with the upper part of the drum. These pipes 11 lead to a common center 27, with which they connect, and this receiver connects with a main steam-delivery pipe, as at 28, which leads the steam to any point where it is desirable to use it. A turnable packed joint, as 29, allows of the movement of the branch pipes 26 with relation to the stationary delivery-pipe 28 and maintains a tight joint during the operation. Having thus described my invention, what I claim, and desire to secure by Letters Patent, is 1. A steam-generator consisting of a revoluble water-chamber, a steam-drum located above said chamber, circulating-pipes connecting the two, means for supplying water to and conducting steam from the apparatus, and means for applying heat thereto.

2. A steam-generator consisting of an annular revoluble water-chamber, an annular steam-drum located above said chamber, circulating and conducting pipes connecting the two, and a screen or housinginclosing said pipes and forming a heating-space above the water-chamber.

3. A steam-generator consisting of an annular horizontally-revoluble water-chamber and means for applying a heating medium thereto, an annular steam-drum located above said chamber, vertical circulating-pipes connecting the chamber andv drum, other horizontal and diagonal connecting-pipes extending above the water-chamber and forming an intermediate heating-space, and vertical and diagonal shields inclosing said connectingpipes.

4. A steam-generator consisting of. an annular revoluble water-chamber having elevated annular rims around theinner andouter periphery, means for supplying fuel to the channel thus formed, an annular steam-drum located above and interior to the inner line of the water-chamber, vertical circulatingpipes connecting the water chamber and steam-drum, horizontal and diagonal pipes extending above the fuel-space and connectiug'the water-chamber and steam-drum, and shields inclosing said pipes and forming a furnace-chamber.

5. A steam-generator consisting of a revoluble circular water-chamber rectangular in cross-section and having a fuel-space formed onthe top, a circular steam-drum located above said chamber, vertical circulating-pipes connecting the chamber and drum, horizontal and diagonal connecting-pipes extending above the water-chamber with an inclosing shield or housing, and a fixed surrounding wall within which the outer periphery of the water-chamber and the top shield turn in close proximity,

In Witness whereof I have hereunto set my hand.

JOSEPH L. GIROUX.
